- Q:What is frequency conversion? What is the function of frequency converter?
- Power factor compensation, energy savingThe reactive power will not only increase the heating power loss and equipment, more important is to reduce the power factor of the power grid leads to the decrease of active power, reactive power consumption in a large number of lines, low efficiency, serious waste of equipment, the use of frequency control devices, the inverter internal filter capacitor, thereby reducing the reactive power loss, increase active power grid.
- Q:There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,
- The boss to the electronic parts store, a duplex potentiometer, resistance and frequency converter converter on you as well, so that the original line after the line on the inverter came up to double the potentiometer, ah, ah ah Wang simple to score
- Q:What does the RUN key on the inverter mean? How do you use it?
- In general, when selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button. Press it, the converter will run, turn or reverse
- Q:How to choose frequency converter?
- 3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor
- Q:Schneider 303 4KW frequency converter F 013 trouble shooting method
- According to the ATV303 user manual,The F013 is a motor overload fault and is triggered by excessive motor current.Suggest:1. monitor the running condition of the converter with the panel (whether the actual running current exceeds the limit)2. check the motor thermal protection settings and motor load (such as motor drive chain bearings, reducer, etc.).
- Q:Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?
- Is the original power inverter direct input three-phase asynchronous motor inverter in inverter internal access first, through PWM electronic converter technology will AC rectifier, inverter, a controllable frequency alternating current at the input to the motor, the motor operation can be controlled by V/F, output torque control and vector control control frequency, change the loop current, realize energy-saving operation, especially the energy saving effect is obvious in the motor at light load is a kind of energy-saving products, has been widely spread and applied.
- Q:Which brand of converter is better?
- Supporting the use of Sinopec group, double coin group and other national key projects, the quality of product quality and good customer service service won the praise of users!
- Q:5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?
- Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.
- Q:What is the function of a frequency converter on an electric motor?
- Mainly for AC motor speed regulation, but also is a smooth stepless speed regulation. You can also implement some specific controls.
- Q:What are the possible causes of frequency hopping overload?
- The meaning of inverter overload protection is that the output current of the inverter continues to exceed the rated current, but it has not exceeded the transient flow point, and the general duration is defined as 1min. The general overload constant torque converter is 150% 1min, variable torque converter is generally 110%120%/1min.
